When you need to make more than just a few burgers, it’s time to pull out a cast-iron flat-top griddle. Lodge and others make the perfect pro flat top that you can either fit across two burners on your stovetop or toss on your grill outside. Which, by the way, is an excellent solution when you’re strapped with cooking burgers on an outdoor propane grill—using a flat top or cast-iron skillet directly on the grill grate will help you produce amazing burgers outdoors. Plus, all that airborne grease produced by the fifty amazing burgers you made for your friends will not end up in your kitchen.
